The First 750 kV RIP Transformer Bushings Delivery in Russia

On 19 April 2016, Izolyator delivered 750 kV AC high-voltage transformer bushings to a Russian customer, Togliatti Transformer Ltd, for the first time in Russia.

The GKTII-30-800/1000 IVUE.686356.705 bushing is designed for the maximum operating voltage of 800 kV at 50 Hz frequency. The nominal current is 1000 A.

Like in other bushings of the company, the proprietary RIP technology was used to make the bushings. It was first introduced and adapted for industrial engineering in 2002–2004.

The porcelain housing with dry filling — compression gel – on top of the RIP insulation is used for exterior insulation.

These bushings are included in the product range of Izolyator plant and were made as yet another consistent step in transition of the entire product range to the solid internal insulation – RIP – as the most reliable and prospective. Thanks to this technical policy, Russia possesses the biggest experience of RIP bushings of various applications in the world.
